In one paragraph
This code says the reading arriving from the oven temperature sensor or the control and the wiring between them fell outside the band the control is built to trust. The control stops the heat rather than work from a reading it cannot trust, so the cycle will not finish while the code stands.

| F3 E1 | There may be a problem with the Oven Temperature Sensor, the Control, or the associated wiring. |
What an owner observes
- Temperature drifts, or the display disagrees with the food — A probe reading a few ohms off is still inside its window, so the cabinet runs cool or hot before the code ever latches.
- The fault comes and goes with temperature — An intermittent connection opens as the metal expands and closes again when it cools, which is why the code often arrives part-way through a long cycle.
- NEAR MISS - nothing heats and no code shows at all — That is a power or element fault rather than a reading fault, and it belongs on the page for that symptom.
Causes, and why they rank that way
- A loose or corroded connector at the sensor — Ranked first because it is the failure that needs no part: the probe is fine, the joint carrying its signal is not, and heat cycling at the back of the cavity is what works a pin loose.
- The board input itself — Last, and deliberately last: an input stage fails far less often than the circuit in front of it, and replacing it first is the expensive way to find out the connector was loose.
What to check first, second and third
- Follow the harness for rub marks where it crosses metal — A witness mark tells you the fault is in the wire, not in the part at either end.
- Only then treat the board as a candidate — Order matters because every check above is free and the board is not.
What to try before calling
- Clear the code with a full power-down — Switch the breaker off, let the control lose its stored state, then switch it back on and start a short cycle.
About 5 min
- Run the shortest cycle the appliance offers and watch for the code — A short cycle that stays clean while a long one fails tells a technician the fault is thermal.
About 20 min
- STOP HERE if the next step is a meter across the probe terminals — That means a panel off and a connector back-probed, which is where an owner check ends and a service call begins.
What to do before any panel comes off
Safety
Unplug the appliance or switch off its breaker before removing any panel - a capacitor can hold a charge after the power is off. Leave every switch and interlock wired as the manufacturer fitted it: they are what stops the appliance running in a state it should not.
Where an owner stops and a technician starts
Call straight away if you smell hot insulation or see discoloured wiring at the back — a connector hot enough to discolour is arcing, and that is a different and more urgent problem than the reading the code named. In the ordinary case, call once the code survives a full power-down: a repeatable reading fault is a probe, a harness or a board, and telling those three apart needs a meter and the resistance table for that model line.
